Abstract

The utility model relates to a gantry crane with a rapidly replaced pulley, which relates to metallurgic hoisting transport machinery. The utility model solves the problem that replacing the pulley in the gantry crane needs long time. The gantry crane comprises a cross beam, a hoisting fork hinged with the cross beam, a plate hook hinged with the hoisting fork and a spacer bush and the pulley which are connected through a pulley shaft. The gantry crane is characterized in that the pulley shaft is also provided with a side plate; the side plate is also provided with a shaft hole connected with the cross beam; the spacer bush, the pulley and the side plate are connected by the pulley shaft to form a pulley device; and the pulley device connects the shaft hole with the cross beam on the side plate together through a connecting shaft. The utility model overcomes the defect that timing is needed and lots of time is spent when the pulley is replaced for the traditional gantry crane.

Description

Gantry suspender of fast changeable pulley

Technical field

The utility model relates to metallurgical handling machinery, particularly hoisting crane gantry suspender.

Background technology

At present, the employed gantry of crane for steelworks use suspender is shown in Fig. 5,6,7,8,9: it by plate hook 1, hang fork 2, crossbeam 3, sheave shaft 4, spacer 5, pulley 6, equilibrium arm device 7 etc. and form, described sheave shaft 4 is directly installed on the crossbeam 3.When changing pulley 6, need earlier sheave shaft 4 to be split out from crossbeam 3, in the process that sheave shaft 4 splits out from crossbeam 3 gradually, successively pulley 6 and spacer 5 are split out from sheave shaft 4; Reload in the process of crossbeam 3 at sheave shaft 4 then, newer pulley 6 and spacer 5 are contained on the sheave shaft 4 successively; After pulley 6 all installs, sheave shaft 4 is in place and fixes.Adopt gantry suspender of existing structure, pulley 6 of every replacing needs 4-8 hour (do not contain tear open, time of reeve), has a strong impact on user's ordinary production.The user is in order to guarantee ordinary production, and the job placement that all will change gantry suspender middle pulley 6 is at hoisting crane or manufacturing line between turn(a)round.If will cause pulley 6 accidental damages like this, can't in time change, for safety in production hides some dangers for or pulley 6 can also normally use but must change, cause waste in the set time.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of gantry suspender of fast changeable pulley is provided, and solves long problem of gantry suspender middle pulley replacing time.

The utility model is achieved through the following technical solutions its goal of the invention.

A kind of gantry suspender of fast changeable pulley, comprise: crossbeam, hang fork with the crossbeam pivotally attached, with hang fork pivotally attached plate hook, by sheave shaft bonded assembly spacer and pulley, it is characterized in that: side plate also is housed on the described sheave shaft, and side plate also is provided with and crossbeam bonded assembly axis hole, form pulley gear by sheave shaft connection spacer, pulley, side plate, described pulley gear links together axis hole on its side plate and crossbeam by adapter shaft.

The utility model compared with the prior art because pulley is assembled into independently pulley gear parts by sheave shaft, spacer, side plate, the user can assemble these parts of several covers in advance as spare part.In case find the pulley in the suspender of gantry damage is arranged, only need adapter shaft is split out, the direct pulley gear that more renews installs adapter shaft and gets final product.The utility model has overcome when existing gantry suspender is changed pulley to be needed regularly and time-consuming shortcoming.
